Washington (CNN) - Around half the public says they support another congressional investigation into the Benghazi attack, according to a new national poll.

The reason?

The ABC News/Washington Post survey indicates that nearly six in ten say the Obama administration has tried to cover up the facts on the September 11, 2012 attack, which left U.S. ambassador to Libya Chris Stevens and three other Americans dead.

Washington (CNN) - The 2016 presidential election's some 2 1/2 years away. Even the unofficial start of the next race for the White House is still five months away. Yet Hillary Clinton has been, and remains, the object of Republicans' obsession.

Much of their criticism of the former secretary of state focuses on the September 11, 2012, attack on the consulate in Benghazi, Libya, which left U.S. ambassador to Libya Chris Stevens and three other Americans dead. The incident - the first time a U.S. ambassador had been killed on duty in more than 30 years - happened during Clinton's watch as America's top diplomat.

(CNN) - The vast majority of Americans say Vladimir Putin's not honest or trustworthy, but according to a new national poll they don't compare the Russian president's actions in Ukraine with the land grabs in the years leading up to World War II by Germany's Adolf Hitler.

A Quinnipiac University survey released Wednesday indicates that only 24% of the public equates Putin's annexing last month of neighboring Ukraine's Crimea peninsula with Hitler's actions, with 51% saying that's too strong a comparison. Just over one in five admitted they don't know enough about pre-Second World War history to answer the question.
